jet-to-jet drop mass uniformity is required in many applications to eliminate banding When the
specific gravity is 1, 1picoliter (pL) = 1 nanogram (ng).
Drop Velocity - The speed at which a drop of jetting fluid travels from the orifice plate to the receiving
medium.
Encapsulated Postscript File (EPS) - An Adobe graphic file format for high resolution images; it translates
graphic and text into code that tells a printer to print in the highest resolution possible and also has
low resolution view files for quick screen viewing.
Encoder - An encoder is a device or transducer that converts linear or rotary motion information into
uniformly spaced incremental signals.
First In First Out (FIFO) - A form of low-level memory (for example, a shift register. Used in the data path for
temporary storage of bitmap data on its way to a print head.
Fire Pulse - A high voltage electrical signal of precise shape, amplitude, and width, causing a jet to eject a
drop. Also called a drive pulse.
Firmware - Embedded software, i.e., software that is not loaded from a storage device at startup, but instead
resides on the board or in the chip.
Fire Pulse Amplitude (FPA) - The peak voltage of a fire pulse.
File Transfer Protocol (FTP) - The language used to facilitate the transfer of files from a server on the
Internet to another location, such as a desktop computer or another server.
GIF Graphic Interchange Format - An image format type generated specifically for computer use. Its
resolution is usually very low (72 dpi, or that of your computer screen), making it undesirable for
printing purposes.
Gradient - Color in shades from one starting point to another gradually blending in between. A grade change
in a hue. It is a transition of color, creating a blended change between screen percentages of a
single color or between two different colors
Grain - The direction in which the paper fiber lie.
Head Drive Electronics Module (HDEM) - This is the component of the Apollo PSK that creates the high
voltage drive pulses. It is programmable for pulse amplitude and width, as well as rise and fall time.
Hypertext Markup Language (HTML) - A series of formatting commands that describes the components of
graphics and text material presented on the World Wide Web in a consistent manner
Image Area - Portion of paper on which ink can appear.
Image - Usually a photograph that is “translated into a bitmapped” image by scanning Ink Jet Printing
Method of printing by spraying droplets of ink through computer-controlled nozzles. Also called jet
printing.
Initialization File - A file, usually with the extension .INI, that sets startup variables for an application
program.
Large Format Printing - refers to large sized prints, typically A1 sized or larger, produced in full color
utilizing full color digital ink jet printers.
Materials Safety Data Sheet (MSDS) - This is a document which describes the potential safety hazards of a
chemical, liquid or solid, and instructs how to handle it safely and how to respond to exposures or
spills.
Meniscus - The curved surface at the top of the water column, or at any interface between a liquid and a
solid. Nozzles have a meniscus, whose shape and position are set by a slight negative pressure in
